Color plays a big part in films. It can really help to set the mood and tone of what is to come and really can just make a scene really come to life. For example if something happy is happening you would genuinely lean to brighter colors and when something more serious or sorrow is happening you would lean more to darker colors. A prime example of this is trolls, seen as happy fun, loving, and energetic the singing tiny trolls are bright colors. Whilst the big trolls which are shown as sad depressed ogres are dark colors usually grey and even their community has little to no color whilst the tiny trolls are in a vibrant, colorful, and lively community.
